Larian was named after his dog, Lar. During the development of Divine Divinity, the programmers sneaked in a dog called Lar to see if they could get it past unnoticed (IIRC it was a bet beforehand). In one of the inns you could find a dwarf, and with appropriate dialog choices could get him to leave the room (allowing you to get a scroll off the table). If you left and returned later, there would be a dog named Lar there.

Both accounts are the same person. When the new forum software was installed and everything transferred over / imported, there was a problem with the 'Lar' account. Since that was the only one affected (something about being the first account after a couple test accounts that had been deleted), it was easier and probably much faster to create another account than to track down and fix the problem.
