The short version
Marcus Webb is a Sagittarius Sun with a Taurus Moon and Virgo rising. The Sun says what you are here to do, the Moon what you need while you do it, and the rising sign how you come across on the way in.
In practice: you pursue what matters to you freely and on principle, you settle only when life gives you steadiness and sensuality, and people meet a Virgo manner first — analysis, craft — whether or not that is the whole story.
Your Sun is in the 4th house, so the work shows up through home and family; your Moon is in the 9th, so travel, study and belief is the room you retreat to.
Temperament
The chart leans Earth and runs lightest on Air. Earth is your default setting; Air is the one you have to choose on purpose, and often the quality you are drawn to in other people.
Mutable is the dominant mode: you adapt things, which makes you useful everywhere and settled nowhere.
See-saw shape. Two groups facing each other: a life of balancing opposites.
Most of your planets rise on the eastern side: you set your own terms more than you respond to other people's. Most of your planets are below the horizon: the important work is private, and the public version comes later.
Placement by placement
Sun in Sagittarius, 4th house. Identity and vitality expressed freely and on principle — optimism and freedom, with bluntness as the cost. It plays out in home and family.
Moon in Taurus, 9th house. Mood and needs expressed slowly and for keeps — steadiness and sensuality, with comfort as the cost. It plays out in travel, study and belief.
Mercury in Scorpio, 3rd house. Thinking and conversation expressed privately and all the way down — intensity and privacy, with transformation as the cost. It plays out in siblings, errands and messages.
Venus in Capricorn, 4th house. Love, pleasure and money expressed patiently and toward something solid — ambition and discipline, with reserve as the cost. It plays out in home and family.
Mars in Virgo, 1st house. Drive, desire and anger expressed carefully, with an eye for what is wrong — analysis and craft, with a critical eye as the cost. It plays out in self and body.
Jupiter in Virgo, 1st house. Growth, luck and excess expressed carefully, with an eye for what is wrong — analysis and craft, with a critical eye as the cost. It plays out in self and body.
Saturn in Virgo, 1st house. Limits, duty and time expressed carefully, with an eye for what is wrong — analysis and craft, with a critical eye as the cost. It plays out in self and body.
Uranus in Scorpio, 3rd house. Surprise and liberation expressed privately and all the way down — intensity and privacy, with transformation as the cost. It plays out in siblings, errands and messages.
Neptune in Sagittarius, 4th house. Dreams, fog and longing expressed freely and on principle — optimism and freedom, with bluntness as the cost. It plays out in home and family.
Pluto in Libra, 2nd house. Power and deep change expressed through other people and by weighing both sides — balance and partnership, with hesitation as the cost. It plays out in money and possessions.
North Node in Virgo, 12th house, retrograde. Direction and fate expressed carefully, with an eye for what is wrong — analysis and craft, with a critical eye as the cost. It plays out in solitude, secrets and rest.
Chiron in Taurus, 9th house, retrograde. Chiron expressed slowly and for keeps — steadiness and sensuality, with comfort as the cost. It plays out in travel, study and belief. Retrograde at birth: you work this one out inwardly first and only later show it, usually better than people who had it direct.
Lilith in Virgo, 1st house. Lilith expressed carefully, with an eye for what is wrong — analysis and craft, with a critical eye as the cost. It plays out in self and body.
Who runs the chart
Virgo rising makes Mercury your chart ruler, and it sits in Scorpio in the 3rd house. Wherever that planet goes, the chart follows: your life keeps returning to siblings, errands and messages.
No planet rules its own sign, so the chart settles into a mutual-reception loop: Mercury → Pluto → Venus → Saturn → Mercury. Power circulates rather than resting anywhere.
How the parts are wired
Moon trine Mars (0.1° from exact). Moon and Mars cooperate without being asked. It is a talent, and because it costs nothing you may not notice you have it.
Jupiter trine Chiron (0.8° from exact). Jupiter and Chiron cooperate without being asked. It is a talent, and because it costs nothing you may not notice you have it.
Sun square Jupiter (0.9° from exact). Sun and Jupiter work at cross purposes. The friction is productive: it is where most of your effort, and most of your results, come from.
Neptune sextile Pluto (1.2° from exact). Neptune and Pluto offer each other an opening. It works when you take it deliberately; it goes quiet when you do not.
Venus trine Mars (1.6° from exact). Venus and Mars cooperate without being asked. It is a talent, and because it costs nothing you may not notice you have it.
Moon trine Venus (1.7° from exact). Moon and Venus cooperate without being asked. It is a talent, and because it costs nothing you may not notice you have it.
Mercury conjunction Uranus (2.5° from exact). Mercury and Uranus act as one. You rarely feel them separately, which is a strength until you need one without the other.
Saturn sextile Uranus (3.5° from exact). Saturn and Uranus offer each other an opening. It works when you take it deliberately; it goes quiet when you do not.
Sun square Mars (3.6° from exact). Sun and Mars work at cross purposes. The friction is productive: it is where most of your effort, and most of your results, come from.
Neptune square Lilith (3.7° from exact). Neptune and Lilith work at cross purposes. The friction is productive: it is where most of your effort, and most of your results, come from.

Off the zodiac
Venus is out of bounds: beyond the Sun's own declination limit. Out-of-bounds planets behave without reference to the usual rules, for better and worse.
Declination contacts: Sun parallel Neptune; Moon parallel Jupiter; North Node parallel Ascendant; Jupiter parallel Ascendant. These act like conjunctions and oppositions that the zodiac wheel does not show.
