OH, one thing
Please KILL the undead you had targeting you when you're done with a training session.
If you don't they'll either be off in the middle of nowhere (if you trained on the coast), or will try to chase after you (if you recall away), and end up on a coast.
Either way, that will reduce the amount of spawn in the city, and prevent other people from having the creatures to train on or kill, if you don't get rid of them.
