Dungeon Master Series by Eric Vall

What would you do if you were the most powerful dungeon deity in the world and the bindings keeping you trapped within your dungeon were broken? Would you escape? Would you acquire a party of beautiful female minions? Would you use your new minions to conquer other dungeon deities, consume their magic, and grow even more powerful? Would you take over the world? Would you then take over the heavens and destroy the gods? Yes, you would do all of the above. This novel contains harem elements.

What would you do if a sniveling slime ball of a king tried to steal one of your harem members/minions? Would you stand for his insult? Or… Would you kill all of his supporters, take his riches and kingdom for yourself, and rip every last ounce of stolen power from his body? Yeah, pretty sure you'd do the second one too.

What would you do if the ruler of the frozen north land kingdom tried to make one of your faithful minions marry someone else? Would you that happen? Or would you use your dungeon deity powers to dig under his land, invade his castle with your horde of monsters, and warm your soul with the sounds of his dying screams? Come on. It’s the third book. We all know what you would do.

What would you do if a group of usurpers tried to murder your minion-wife and take away your kingdom? Would you destroy them, follow them home to their sovereign island, kill all the gods they worship, and then conquer their land? Yep. You would do that, and you’d laugh the entire time. The Master becomes even darker as his power increases.

Master and his faithful and loving minions have been through dozens of dungeons, battles, and death-defying challenges. Both the fallen god and his women have grown their powers significantly, and now they have fixed their sights on Baudouin, the power hungry king of Tintagal. They intend to destroy him and nothing will stand in their way. Not even another group of fallen gods who may be just as powerful as Master.

For months, Master and his loyal and beautiful minions have battled the sinister mage Tuzakeur across the world in a winner take all race for unlimited power. On the island of Canarta, Master and the sorcerer will have their final confrontation, but there is one thing neither of them accounted for: Canarta is home to the world’s last living dragon, and it doesn’t like intruders.
