Steem integrated MMORPG.

The lore:

Chibera, a land that is still recovering from being torn apart and mutated by an explosion that was caused by a mana experiment centuries ago. Because of this accident, a tree was mutated into what is now called the world tree, along with the mutation of humans, elves, dwarves, and animals which lead to the rise of multiple new intelligent bipedal species.

Some races are now fully dependent on the mana for technological, economic, cultural reasons and some even need to consume it just to survive. This has caused a rift between some of the factions and a fight for control over as much of the resource as possible. The only mana sources now in the world are hard mana crystal deposits and the power that the world tree provides which is the only replenishing resource. This has lead to factions fighting for the resource for their own selfish reasons.
