Umbra - The Last Summoner

As the sole summoner, step into the mystical realm of Umbra to rescue it from the encroaching demon army emerging from dimensional rifts.
To end this invasion, call upon 60 diverse heroes, each with unique abilities, and engage in strategic, round-based RPG battles against more than 160 monsters and demons.

Immerse yourself in vast landscapes, tackle over 100 side quests, conquer colossal boss monsters, and venture through 5 distinct rifts into the demon dimension.
Your epic journey awaits as you explore, battle, and unravel the mysteries threatening the land of Umbra.

The game is a very open RPG game that currently is split into 15 big areas.
The player plays as a summoner, who can summon heroes to fight for them.
Soul energy is used to summon more heroes, weapons, and runes to strengthen the heroes.
The player can collect soul energy by winning battles against monsters or demons, by finishing quests, or by exploring the world.

The battle system is round-based and utilizes action points that are used depending on the selected attack. Items are usable and monsters, heroes and attacks have elements that are strong or weak against certain other elements.

Each NPC is fully intractable and has its own little dialogue tree.
Some of them give quests, others just talk to the player, and again others are traders.
The main quest follows to hero on their journey to fight against demons lords, who are attacking the land.
Each demon lord lives in a „rift“, which basically is the world owned by the demon lord
