Lore
The Bermuda Triangle was never a myth, it was a shadowline nexus deep underneath the Atlantic Ocean. For the most part, the things that escaped this astral gate were benign (like Nessie), but now something dark and predatory known only as The Adversary hunts the seas... and ocean denizens are scared to death.
One of those inhabitants, a psychic sea anemone, wants to do something about it. Summoning an ectoplasmic goo body to traverse the surface, Viscous is desperately trying to summon the Patrons in order to keep The Deep safe from the horror that lurks below.
Versatile to learn · Deep Sea Interpreter
Viscous vexes his opponents through clever evasion and strategic uses of healing, enabling him to withstand the most brutal of enemy attacks.
