The entry to the fortress was the main problem. Although it wasn't as exaggerated as the one facing the other side, it was practically impossible to do so for a small team.
To resolve it, Kyros sent Querk Stonefist and a few disguised soldiers to pretend to be the Viscount squad returning from the intense battle that led to a defeat. The moment the guards saw it, they hesitated. Kyros even heard the discussion.
"It's Querk Stonefist!" A guard identified.
"Open the gates!" The leader of the platoon immediately ordered.
"Weren't they confirmed to be dead? Many of his squads were found among the remains of the Viscounts he was with!"
"Close the gates!" The leader ordered again.
"But his body wasn't found there! He's alive!"
"Open the gates a little!"
The opening gave Querk and the group a chance as they suddenly rushed inside and killed the group. Kyros shot several arrows with Martha to kill the group.
