In the rule Avatars, immediately before the text “a home Tier”, add:

a star sign (which must be a valid value based on the Tiers equal to or lower than that Avatar’s Home Tier)

Add the following to the body of each Tier Rule (except for the one labelled Tier 9):

The available Star Signs in this Tier are:

And then for each Tier Rule according to number add the following immediately after:

1: Leonis (The Lion), Ursida (The Bear),
2: Serpenta (The Serpent), Felina (The Cat),
3: Lupis (The Wolf)
4: Panthera (The Panther)
5: Draco (The Dragon), Equinus (The Horse)
6: Avis (The Bird), Canis (The Dog)
7: Corvus (The Crow), Cetus (The Whale), Aquilus (The Eagle)
8: Lynx (The Lynx), Apis (The Bee), Delphina (The Dolphin)

Amend the rule Skywriting to read as follows:

As a weekly action, a Mindjacker may privately message the Ascendant an instruction to generate a specific Portent from the prompt “The stars are (x)”, where (x) is a Star Sign that that Mindjacker has access to based on their Level. The Ascendant shall, as soon as is practical after receiving the message, generate a Portent of the form “(name) was incongruous under the stars of (x)”, where (name) is the full name of an Avatar whose Occupancy Tier is the Tier with which star sign (x) is associated and whose star sign is not (x), if possible and if it does not duplicate an existing Portent (otherwise they do nothing).
