It is a defense game to protect the castle from enemy attack. The enemy's attack will become stronger and stronger, but you will become much more powerful with upgrades to your defense.


The protagonist is a brave warrior (Kaytsumik), belonging to the Umik tribe. All descendants of this tribe are distant cousins ​​to the dwarves and have red hair.

Kaytsumik had a beautiful amulet, a traditional relic from her family, in which it had been kept for generations. This amulet was very powerful, but its power fell asleep after a big battle in the past and, only a person belonging to the Umik tribe and pure in heart, could again awaken this great power.

Umik dominated Gray Magic, but, being practically extinct after several battles, the tribe forbade the use of any kind of magic, as they believed that magics attracted wars. After some intriguing events, Kaytsumik was accused of practicing Black Magic and was expelled from her tribe.

After being expelled, Kaytsumik created a big castle, and discovered that the amulet grants immortality (a fact known after resuscitating her son who had died during childbirth). With that, the news spread and a powerful witch (Morttuks) was willing to take the castle in search of the relic. Morttuks can revive the most powerful warriors of all eras to fight for her. So Queen Kaytsumik needs to strengthen her defense and fight to defend her castle!
