UPDATE!  Now with the actual Dire Bear Mount pics!

Much recent discussion has centered on the The Shadow Odyssey premiums, especially the dire bear mount and pet which is only available with the retail box version of the expansion.  This item scales with the level of the caster:  at low levels it's a pet, and as your character grows it becomes a mount, becoming more and more useful to you.  Allakhazam has acquired exclusive pictures and video of the level 80 Ykeshan Warbear!
