Knight-Commander Martel is first encountered during the meeting with Divine Beatrix III at the Grand Cathedral in Val Royeaux, where he accuses the Seekers of being reckless by not asking for Templar re-enforcements in their attack on the Blood Mage ritual.

Later at Grand Cleric Callista's request, he is dispatched to lead the hunt to apprehend the renegade Seeker Cassandra Pentaghast and Regalyan D'Marcall. While hunting the pair, Martel accidentally reveals that he is Frenic's co-conspirator in the Chantry ranks. Although the two of them elude Martel, he anticipated that they would attempt to alert the High Seeker and went to the Seeker stronghold and murdered Aldren before he could alert the Divine of Martel's treachery, framing Cassandra and Regalyan for the deed.
