Siobhan: Declare herself Imperatrix of Tygara and rule with an iron fist. That was a joke...maybe, but she may become more of a ruler. Further develop the Order of Fire, expand Firemane's and Tygara's influence. Steal [member="Valiens Nantaris"]' Twi'leks because Sio's massage skills are superior.
Elpsis: Have her grow up a bit. She has power and combat experience, but lacks maturity and is presently kind of Battering Ram Junior. Tying in with that I'd like to develop her more as a seer. Help [member="Laina Silvias"] return to and reform her tribe. Do stuff with mummy and Tempest.
Enyo: Write the confrontation with Siobhan. Have Enyo free herself from Archangel's clutches and go adventuring with [member="Amara Zarides"]. The clone shall step out of her mirror's shadow. Maybe take over a portion of Archangel one day. Considering her being a mercenary for a while - good way to hop into invasions and skirmishes.
Moira: Burnt-out on her, so she'll mainly appear as a villain for the story arcs of Firemane and the personal plots of Enyo, Amara etc.
Naamah: Continue her redemption story (no going Jedi though) and get her campaign of vengeance against Archangel on the way. Do more stuff with Cora Passek and Mirien Valdier. May confront her more directly with her sins by having her run into victims.
Sumiko: Develop and grow her company, produce evil alchemy stuff and give her a power base. Do evil stuff with [member="Matsu Xiangu"] and have a big rivalry with Phylis Alince. Maybe one of Sumiko's apprentices will challenge her in time.
Qual'Zyanya: Give her some actual development and make her more independent. Have her start building up a power base amongst the Xioquo and on Tygara. This may eventually conflict with her allegiance to Sumiko.
Kaida: Plagiarise Sherman quotes. Have her return to Kaeshana and be confronted with the fallout from the Exodus. Do stuff with Coryth Elaris and explore Kaida outside of the line of duty a bit. Use her more outside of Eldorai affairs.
