Because Marus got distracted

Marus was ready to go in Mira's chambers. He was ready to dip the paladin in an ocean of pleasure and **** her to beg for more. He sent his unsatisfied **** away, and prepared to teleport to his ideal maiden but in the same moment one of his guard entered in his room

"Master" He said regaining his breath " We are under attack. We must gather all our forces and need you as our commander"

" How dare you, ****, to enter my private chamber without serious reason? I don't care about meager counterattacks from the Kingdom of Arlain especially after they lost Mira. You will be punished for distracting me. Now begone"

"But master" scared guard answered" We are attacked not by human kingdom. Taracus moved his forces to your mighty fortress. "

This was bound to happen some day. Two demons can't be friendly neighbors but Marus never expected that Taracus, demon of wroth will attack that soon. Did he defeat an elven forest so quickly? Or is he crazy enough to wage war on two fronts? Speaking about two fronts. Most of Marus forces are tied in the siege of the capital of Arlain. In no way he can bring them home in one week that Taracus need to reach his fortress from the border. Neither he can stop his advance with available reserves. His fortress will see the first real combat, he should prepare to defend against an **** with understrength garrison
