The Reflected Ones are a thrallband of the Thousand Sons Traitor Legion. The Sorcerers of the Reflected Ones view realspace as an imperfect mirroring of the Warp, and seek to scour the galaxy of its impurities by weaving world-spanning mutagenic spells. The ranks of their enemies devolve into Chaos Spawn and braying Tzaangor herds before the Thousand Sons even set foot on the battlefield.
The Reflected Ones thrallband's colours are azure trimmed in silver. They also wear light yellow robes and tabbards.
The Reflected Ones thrallband's sigil is a light yellow Cult of Magic symbol centred upon a field of light azure and trimmed in silver.
