Summary:

Din doesn't want to be Mand'alor. The Darksaber, that definitely does not whisper to him in the middle of the night, refuses to leave his hand. When Din is finally presented a chance to rid himself of it, promised to a Mandalorian he has never met yet it yearns for him, Din doesn't hesitate to make a deal.

That may lead to some problems. Din should have hesitated, considering that promise may or may not have come from the ghost of an ancient Mand'alor capable of wizardry.

Oh well, at least this cop is nice and helpful.

TLDR : Din doesn't read the fine print, gets flung through space and time, goes through puberty twice as a result, and crash lands at a pivotal point in Jaster Mereel's Journeyman Protector career. Jaster has thoughts about this. Maybe too many thoughts.
