Shin had already thought of five major steps that would let him and his clan successfully escape or evade the threat.
Step one - informing all the higher-ups of the clan and encouraging them and unifying them.
With this step, Shin made sure that his strong men remained with him. The more the number of stronger beasts, the safer he would feel.
Step two - returning to the village.
Shin wanted everyone in the clan to return to the village that the dwarves were building. Since it was a centralized place that was deeper in the woods, it would be considerably difficult for other races or groups to find them. Also, the strong monsters present in the forest would act as a preventive measure or barrier for the clan and would slow down the foes.
Step three - leveling up the members and allowing evolution.
