In @FromLostStrength's original timeline, Lorst had stayed in Ylisse and brought his wife and two year old toddler, Anrase Calell, to set up a new headquarter for their noble house. As the Grimleal War struck the world, Lorst left his family behind to aid his friend Chrom and his army in fending off the world destroying/apocalypse-worshiping religion.

When Lorst confronts Validar with Chrom, Lorst looks down at the brands on his hands and the barely visible one on his chest. The normally dark Brands were glowing an eerie reddish purple. Chrom watched in horror and disbelief as Lorst started cackling, two more pairs of eyes opening on his face. Six eyes stared at the descendant of Anri, of Marth with a sickening smile.

Lorst sided with Validar and slew Chrom with a the battle axe he carried often.

Anrase is clueless as to why his father never returned to him and his mother just as Lucina is unaware of who exactly it was that killed her parents and comrades' parents.
