As all know, it's been confirmed that Iroh II was to have a sister who'd be a love interest to Mako.
They were setting her up but obviously she didn't make the cut.
We can only speculate how that could have been like but Bryke is now expecting us to fill in the gaps.
We should, as a community, try to create what this character should be.
How? Suggestions in the comments, the most popular would be put in polls which we will use to come up with the final results for:
Name
Personality
Age
Traits
Bender or Non-Bender
All that good stuff.
Go into the comments and let's get to work!
