Artist's comments summary:
1. The dragon who fought for an offered woman in the boy's story is of course Shyvana's father.
2. The man watching over Shyvana and the boy at the waterfall is the human-like form of Shyvana's father, also probably used when mating with her mother.
3. The bear that attacked the boy is the same species as Tibbers, Annie's ultimate.
4. This story is way before Shyvana meets Jarvan IV. Artist mentions it would be around the same time that Jarvan II was in service, because dragons and half-dragons age much more slowly than humans do.
5. Artist seems to have modeled the boy's appearance after Edward Elric.

Does this mean that the bear IS Tibbers or is just another Shadow Bear?

A shadow bear like Tibbers.
