Triad of One is a visual novel about three bodies (corpses) controlled by a mystery fourth entity; The "entity" who control these, otherwise soulless bodies, make uses the "shadow memories", the skills, the capabilities and even flaws to affirm its will. The elven maiden will provide its Intelligence (INT), the tough dwarf will provide (both physical and attitudinal) Strength (STR) while the last one... the human, will provide Dexterity (DEX).
But "they" will not use these skills for fight, but obtain information from various NPCs across the lands. Each skills will offer two talking options (for a total of six): one of them will allow you to advance, while the wrong one will antagonize the NPC you're talking with... so, pick careful, don't haste, take your time... what the NPCs says will be always the clue for the next right answer! You won't get to pick (or even read) your exact words to use, instead a fix and clear set of choice will represent the approach (and who among the tree) you will take with each NPC.
