From Warhammer 40k - Lexicanum
Laestides was a past Chaplain of the Blood Angels Chapter's 10th Company.
In 456.M40, he and the Sanguinary Priest Rugon oversaw the Blood Angels' Aspirant trials on Baal Primus. Once the selection process was done, they escorted the successful Aspirants to Baal Secundus' Place of Challenge where they would undergo further testing. These Aspirants would be mixed together with those from Baal Secundus, which included a young Luis Dante.
