Elder Scrolls Universalis features many unique groups, several more than Vanilla EU4. Additionally, several lore-based idea groups are available which unlock subsequent idea groups, allowing for goal-directed personalization of ideas. Lore-based idea groups are inspired by the skill trees of elder scrolls games with additional groups, such as colonial empire, jurisprudence, and military tactic ideas added for more flavor and personalization.
