El portal de los dioses ferales (Carl el Mazmorrero, 4)

You failed a mission the moment you received it. Now that's talent! A flying fortress occupied by warrior gnomes. A castle made of sand. A dilapidated submarine protected by broken machines. An enchanted crypt filled with deadly traps. And it was supposed to be easy! A bubble. Four castles. Capture them all and the stairs will open! But things are never that simple… Carl and his team can't do it alone, not this time. They need the low-level dungeon crawlers and the idiots who are surprisingly still alive and also trapped in this bubble. Can they trust them? Welcome to the fifth floor of the dungeon.
