Bones of Baelsor
From Warhammer 40k - Lexicanum
The Bones of Baelsor is Dreadnought armour that belongs to the Flesh Tearers Chapter. It earned its name after the great hero Baelsor fell in battle against[1a] the Bonescar[1b] World Eaters Warband while wearing it. Baelsor's passing also made the Dreadnought armour a relic of the Chapter and many worthy Battle Brothers have worn it since that time. The most recent was Skoraen the Bloodied[1a], until he was killed during the Cryptus Campaign and his death at the claws of Hive Fleet Leviathan left the Bones of Baelsor severely damaged.[1c]
