Spike, the gem person who used to be a gem king before his body was destroyed by the previous Snow King, is one of the gem people who survived the massacre of his people. He survived because of his current weak state.
He managed to slip past the three patriarchs because of his non-threatening power level, while other gem kings were killed. Despite surviving because of luck, he was still going about causing trouble for the Blood Skull army.
He is the one who the first Sun King is in contact with. They are communicating with small leystones, which also survived the purge of the three patriarchs.
The Sun King was in the safety of the South Pole, hovering above a leystone, while Spike was somewhere far underground, standing in front of a small leystone.
The face of the other person could be seen on their respective leystones. The face of Spike was that of a polished blue gem, while the face of the Sun King was a round, bright face of red burning flames.
