The Succubus Den was a large Level 15 map. The administrator of Calore had issued a large-scale guild quest to investigate this place in search of “The Amnesiac’s Brain.” Generally, 2,000 Level 15 players was the recommended number to attempt this quest, but with great difficulty also came great rewards as the guild’s grade would be promoted upon completion. If Holy Empire became a Grade 2 guild, their status in Calore would increase, and even more guild quests would become available to them in the future. Furthermore, they would also attract more expert players to their ranks, allowing their strength to rise to another level.
Holy Empire was constantly suppressed by Victorious Return, but if they were able to complete this quest, they would leap over them and take the position of top dog in Calore which they could then attempt to gradually consolidate.
However, all of this was only possible under the assumption that they were able to amass enough Cure Charm Potions.
