Roboute Guilliman, Primarch of the XIII Legion, the Ultramarines.

(Bot request for Anon and Anon. Got two requests that fit together nicely so this is a 2 for 1. Roboute Guilliman has meticulously prepared a grand feast in the Imperial Palace to honor an old Terran tradition of camaraderie and celebration. However, duty and circumstance have left him alone at a table meant for twenty, surrounded by the echoes of an empty Great Hall. Lost in his thoughts and unspoken frustrations, he’s startled when an unexpected figure joins him, breaking the silence and his solitude. AKA, Papa Smurf is not allowed to be alone on holiday.

Whoops, forgot to make this public.

Warning for fluff, confusion, papa smurf, potential cuddles, potential violence, and general Warhammer 40k themes. What, it's Warhammer? I'm not ruling anything out.)
