The little gnome squinted his eyes up at the elf. His mouth pursed in an expression neither quizzical nor worried. He reached up to the lens that sat in front of his left eye and clicked a mechanism a few times. His eyes lit up in surprise, followed by a deep laugh from the gut. "Ae'lar. Where did you say you got that tattoo again?" The elf looked down at her compatriot, "In the great dwarven city of Ilridun. It's a symbol of the ancestral might that all dwarves share, and says 'Fearless Empress of the Depths' in dwarvish. They wanted me to have it for my heroism in the mines below the city." The gnome's laughter turned to wheezing. He sat down to catch his breath and compose himself before looking back up. "Ae'lar, I hate to tell you this, but that says 'Feckless Empress of the Dafts'."
