Downed Castle Defense

Sael focused on reinforcing the protective shell where the massive roots were still constricting around them, crushing the stone.  Worse, the section of ground they had crashed into had been hollowed out with a maze of tunnels forcing a quarter of the egg shaped sealed castle into the earth.  Already truck sized ants were busy tearing into the stone seeking to burrow into it.  Before he could get control of the situation the entire castle rocked as first one then a second titan beetle slammed into them.  Stone crumbled and the carefully defended murder corridors became useless as new openings were battered into the castle.  The massive Thousand Leg Devouring centipedes crawled onto the castle spewing their caustic venom as they began tearing their way in as well.
