Be an elf.
You try your hardest to be an elf. You fail because you are already a kobold and being an elf is a horrible, horrible idea. Wait, what where you doing?
Oh yeah, sneaking into Cityshanks, the dwarven fortress.
Legend tells the artifact bronze dagger, Tributescar, is hidden deep in the vaults of Cityshanks. It's crafstdwarfship is of the highest quality. It's handle is studded with onyx and silver. On the dagger is an image of a dwarf striking down a dingo using Tributescar. Ever since you were a hatchling you knew, one day, Tributescar would be yours.
You have finally made it up this mountain to the front of the fortress. Now what do you do?
