Editing Brother-Librarian Tiberian Calchos (Ultramarines) (section)

== Notable Missions Prior to Joining the Deathwatch ==

=== 1. The Karthax Rift Incursion ===
A splinter of Hive Fleet Kraken breached the Karthax Rift, threatening a chain of lightly defended mining worlds. Tiberion was attached to a rapid‑response strike force tasked with delaying the Tyranids until reinforcements arrived.

* He erected a series of psychic wards that disrupted synaptic cohesion, causing several broods to fall into disarray.
* His prescient warnings allowed the strike force to avoid an ambush by Lictors, preserving the command cadre.
* The delaying action succeeded, and the Tyranid advance stalled long enough for the arrival of a full Battle Group from Ultramar.

=== 2. The Vharos Reclamation ===
When the agri‑world Vharos fell to a sudden Eldar incursion, Tiberion accompanied the 2nd Company in a counter‑offensive.

* He deciphered the Eldar’s shifting webway patterns, predicting their next strike with uncanny accuracy.
* During the final engagement, he engaged an Eldar Warlock in a psychic duel, severing the xenos’ link to their strike force and collapsing their battle plan.
* The Ultramarines reclaimed the world with minimal civilian casualties, a rare outcome in such conflicts.

=== 3. The Purge of Hive Lormax ===
A Genestealer Cult embedded deep within Hive Lormax triggered a planetary uprising. Tiberion was deployed to assist in identifying and neutralising the cult’s psychic nodes.

* He traced the broodmind’s influence through the hive’s under‑levels, pinpointing the Patriarch’s lair.
* His psychic shielding protected the strike team from the Patriarch’s mental assaults during the final assault.
* The cult was eradicated, and the hive returned to Imperial control within weeks.
