The Crimson Warriors were a Loyalist Blood Angels guild serving in the Arkhona Campaign. After their Chapter Master fell to Chaos, the still loyal members along with the leadership of the 1st Company banished their old Chapter Master and were allowed to rebuild into a new chapter. Now known as The Sanguine Tempest, the remaining loyal sons of Sanguinius continue to wage war on Arkhona against heretics and xenos alike.
