Oh, supporting a transgender orc could be an entire campaign in itself! I’m of the opinion that transgender issues wouldn’t normally be an issue in a world with permanent polymorph, but for an orc? Even if the tribe had a caster of high enough level, becoming biologically female doesn’t sound great in a traditional orc society (assuming they use their women as baby factories to compensate for their high death rate), and that’s also a culture where not fitting in could have lethal consequences if found out. The orc being a mage adds a fun additional wrinkle if she’s capable of casting it herself but refuses until she gets somewhere safe.

So she’d be putting off the polymorph until after the players help her escape the tribe, while the elders attempt to stop them due to her being one of their few competent mages. Then they have to help her find a place in civilized society that looks down on her for all the things her previous culture praised her for.

I think I fell in love with this character already. Thanks for the inspiration!
