- For the defender of Karakas, see Angus MacKenzie.
Angus was a holy man who witnessed a jealous, unnamed planeswalker attack Serra on the Plains of Sursi. He distracted Serra’s planeswalker assailant and ran off with Serra’s dying body. Serra blessed the land with her passing, flooding it with holy power to be a sanctuary against the dark forces that assailed her followers. Angus made her comfortable in her last days and built a temple in her honor: the origins of the Cathedral of Serra. To this day, Serra Angels sometimes spontaneously appear in the Cathedral.
The cantos of the Song of All #1001 to #1020 are known as Brother Angus's Lament. He added them after Serra had imparted her wisdom to him before dying.
