Nah. You won't be seeing the Kraken regularly in the RPG [It's simply too powerful to be a regular NPC or character]. It'll be mentioned in passing. explosions of red water and, on occasion, hellish limbs reaching up from the depths, a massive, unidentified beast breaching the surface of the waves. maybe a small personal plot involving a survivor of an attack [extremely rare]. But nothing more than that. TT and CS have compared its description behaviour-wise to the Doomfang. I'm inclined to think its presence in the RPG will be of a similar nature to that.
But yeah, you don't have to worry about it attacking Steaky [if he ever shows his face in FRPG

And IK, thanks. The Kraken is a very fast creature. much faster than it's tentacled head would have you believe. the shark-like fins are for stability at high speeds. In-RPG, there would literally be no prior warning before a Kraken attack. by the time anyone would know they'd been hit, they'd already be dead or dying, or otherwise too far gone to do anything about it. the survival rate is so small that in the several hundred thousand years they have existed, Krakens are still almost unknown to Asterian historians.
I intend to flesh out a bit of what Asterians know of the Krakens during Seppy's journey for knowledge.
