When Lancelot reached the throne hall in Tigana's Castle, the Succubus Lord had not appeared yet, but he was not the first one to arrive—four fully armed Dwarves were already there waiting.
Lancelot recognized these Dwarves as vaguely familiar, then realized that he had indeed seen them before: when it was decided to establish a Temple of Moradin in the Shattered Mountain Range to house the Holy Iron Anvil, seven powerful Dwarf Warriors had stepped forward, taking on the duty of guarding the Temple.
The four in front of him were of those seven Dwarves; they were all veterans of many battles, skilled in martial arts, among whom the leader was also a Dwarf Priest of Moradin, possessing Divine Arts abilities to protect against toxins and heal life.
Of course, before becoming a priest, he was also an experienced warrior.
"You must be Sir Lancelot." The Temple Guards, all Dwarves, stood up and greeted Lancelot.
