The short version
Iris Calder is a Pisces Sun with a Virgo Moon and Aries 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 imaginatively, with the edges blurred, you settle only when life gives you analysis and craft, and people meet an Aries manner first — initiative, courage — whether or not that is the whole story.
Your Sun is in the 12th house, so the work shows up through solitude, secrets and rest; your Moon is in the 6th, so work, health and routine is the room you retreat to.
Temperament
The chart leans Fire and runs lightest on Air. Fire 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.
Splash shape. Planets spread around the whole wheel: broad interests, versatile.
Most of your planets sit in the western half: your life takes shape through other people, in partnership and response. Most of your planets are above the horizon: your life is lived in public view, whether or not you chose that.
Placement by placement
Sun in Pisces, 12th house. Identity and vitality expressed imaginatively, with the edges blurred — compassion and imagination, with escape as the cost. It plays out in solitude, secrets and rest.
Moon in Virgo, 6th house. Mood and needs expressed carefully, with an eye for what is wrong — analysis and craft, with a critical eye as the cost. It plays out in work, health and routine.
Mercury in Pisces, 12th house. Thinking and conversation expressed imaginatively, with the edges blurred — compassion and imagination, with escape as the cost. It plays out in solitude, secrets and rest.

Mars in Taurus, 1st house. Drive, desire and anger expressed slowly and for keeps — steadiness and sensuality, with comfort as the cost. It plays out in self and body.

Who runs the chart
Aries rising makes Mars your chart ruler, and it sits in Taurus in the 1st house. Wherever that planet goes, the chart follows: your life keeps returning to self and body.
Every planet in this chart reports, sooner or later, to Pluto in Scorpio. That is the final dispositor: the single planet the whole chart answers to.
How the parts are wired
Venus quincunx Lilith (0.5° from exact). Venus and Lilith never quite line up. You keep making small adjustments between them, and the adjusting is the point.
Moon trine Neptune (0.8° from exact). Moon and Neptune cooperate without being asked. It is a talent, and because it costs nothing you may not notice you have it.
Moon sextile Pluto (1.1° from exact). Moon and Pluto offer each other an opening. It works when you take it deliberately; it goes quiet when you do not.
Neptune sextile Pluto (1.9° 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 square Mars (2.0° from exact). Venus and Mars work at cross purposes. The friction is productive: it is where most of your effort, and most of your results, come from.
Sun square Saturn (2.3° from exact). Sun and Saturn work at cross purposes. The friction is productive: it is where most of your effort, and most of your results, come from.
Mars sextile Lilith (2.5° from exact). Mars and Lilith offer each other an opening. It works when you take it deliberately; it goes quiet when you do not.
Pluto trine Lilith (2.7° from exact). Pluto and Lilith cooperate without being asked. It is a talent, and because it costs nothing you may not notice you have it.
Venus trine Chiron (3.0° from exact). Venus and Chiron cooperate without being asked. It is a talent, and because it costs nothing you may not notice you have it.
Venus square Pluto (3.2° from exact). Venus and Pluto work at cross purposes. The friction is productive: it is where most of your effort, and most of your results, come from.
Patterns
Grand Trine: Moon, Mars, Neptune. A closed circuit of ease. Reliable talent, and a temptation to coast inside it.
T-Square: Mars, Pluto, Venus. Two planets in opposition, both squared by a third. The third one is where the pressure lands and where the work gets done.
T-Square: Neptune, Lilith, North Node. Two planets in opposition, both squared by a third. The third one is where the pressure lands and where the work gets done.
Mystic Rectangle: Mars, Lilith, Pluto, Neptune. Oppositions braced by trines and sextiles. Tension with a built-in release valve.
Kite: Mars, Moon, Neptune, Pluto. A grand trine with a handle: the talent finally has somewhere to go.
Off the zodiac
Uranus 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: Mercury contraparallel Ascendant; Lilith contraparallel Midheaven; Venus contraparallel Mars; Mars parallel Chiron. These act like conjunctions and oppositions that the zodiac wheel does not show.
