Mythril beings

Mythril is Highest-categorization of power a creature can obtain, originally created by the Three Mythos. To be Mythril isn't necessarily physical/destructive power, however. You can also gain by the rank via Mythril-level resistance, telepathic power, potential, etc. Exceptions can be made under certain circumstances. An easy way to determine if someone's Mythril is to ask: "Can they destroy a galaxy and/or all life within it?" If so, then yes!
