You were swallowed by the tentacled creature... but instead of becoming another victim YOU TOOK CONTROL!
Now the eldritch mass obeys you. Your body is still lost somewhere in the depths, but with the help of your brilliant (and curiously eager) elf researcher girlfriend, you might just claw your way back to freedom.
