@L0g41n: What, didn't the IC post answer your questions?
Srsly, though: Unit is a Warforged Artificer. Marisa is his familiar, at least by the rules. Ask her in-character if you want her opinion. So, leader. Not very leader-ish, though.
Xyrhanna is our defender. If you want to know more, you'll have to ask her yourself.
The elf is a striker, I think. Apart from that, I know practically nothing.
I need to write up my character sheet on myth-weavers. DM Goddess, DM Ashe: Click Sheets at the top to access your character sheets. You can create as many as you want, and associate one of them with the game (in Goddess' case). You can also take a look at how others have made their character sheets. If you don't want to use the on-site tools, you can also keep using your old tools. All the power to the GM.
There's a lot of tags available for your convenience when writing posts. I tried to find the page that explained all of them, but have failed so far. L0g41n: Do you have any clue where I can find it?
