Preparation complete, Malin opened a short-range teleportation rift here. It should be noted that rifts and portals are similar, but different. Portals are safer but also create more disturbance; any decent Immortal Master or Mage can sense the opening and passage of a teleportation portal once they are at the fifth ring. Usually, strange creatures are involved.
However, if it's a rift, it is much harder to detect, but fewer people can pass through it compared to a portal.
Changing the person who opens the portal, the person in charge would probably be afraid of this rift, worrying if people might suddenly disappear halfway through. However, as long as this rift was opened by Malin, he led his people through without hesitation and surprisingly found that the group was already standing on top of a ruin near a small square.
