Changing it to 9 wouldn't really help for me anyways, so keeping it at 10-11 is fine. I won't be able to post then, but i could make my decisions clear ahead of time, if i am mafia.
I will join.
I'll just leave a few suggestions for characters here:
Name - Title - Power
Mafia (meteors):
Lin - Meteor High Command (first) - in the case of a tie on Mafia killing votes, the side with the highest High Commander wins the vote.
Solaris - Meteor High Command (second) - see above, but one level lower than Lin's (only active if Lin has died)
Sirius - Meteor High Command (third) - see above (only active if Lin and Solaris have died)
Simon & Tara (i think those were the names of those Meteor grunts) - Lovers - Two separate players. If one dies, so does the other. (similar to the standard mafia game's lovers, but on the Mafia's side)
Filler names: Taka, ZEL, Elias, other meteor grunt names
Civilians (others)
Ame - High Command - in the case of a tie on civilian's kill votes during the day, the side with Ame on it wins the vote. Ame's role is known to everyone.
Anna - Psychic - Can inspect a person's role every night (or simply be revealed if they are Mafia or not)
Victoria - Guardian - Can protect a character from a Mafia attack during the night. Can choose self, but can not choose the same character (not even self) twice in a row.
Fern - Betrayer - Appears as a civilian, but if killed by the Mafia at night, will become a Mafia member instead of dying (some kind of message such as "no one was killed at night, but a certain person has betrayed the Civilians")
Vero/Alice - Protagonist - The protagonist never dies (can not be killed by Mafia during the night)
Kiki - Sensei - Can revive and kill a person at night, both only once. Can revive self if revival has not yet been used.
Shade - Entity - Can kill someone every even night (separate from the mafia and civilian kill votes).
