Gravity is set to host the 'Prontera Square Invitational', a user invitation event for its MMORPG Ragnarok Online, on May 2nd. This event was organized to commemorate the 24th anniversary of Ragnarok Online's commercial service in Korea and to express gratitude to users during Family Month. The event will be held at the On-Mom Theater in Mapo-gu, Seoul.

The event consists of two parts, starting with an opening address, followed by a presentation of the 2026 vision and roadmap for Ragnarok Online, an introduction to new Ragnarok IP titles, and a Q&A session. Key figures, including the lead producer, creative director, and members of the planning and business teams, will be in attendance to communicate directly with users. Gravity is inviting a total of 80 people, including the winners selected from the pre-registration pool and their families. For users unable to attend in person, the official virtual YouTuber Pring Cotton will host a live broadcast on the official YouTube channel.

A variety of events will be prepared at the venue. A prize draw will be held to present special gifts based on memories tied to Ragnarok Online. Additionally, participants can engage in on-site events such as Ragnarok trivia, photo zones, and instant photography; those who upload proof shots to social media will receive in-game cash and items. There will also be a Pring Cotton channel follow event and a special gift distribution of Poring bags for users visiting with their children.

Kim Sung-jin, Business PM for Ragnarok Online at Gravity, stated regarding the event, "We planned this event to share our future plans and collect feedback on-site to provide a more satisfying service, as a token of gratitude to the users who have loved Ragnarok Online for a long time." He added, "As this is an event where families are also invited, we hope you create happy memories with Ragnarok Online, and we ask for your interest in the live broadcast for those who cannot attend in person."
