For a limited time, Sky: Children of the Light players can interact with the Season of Sanctuary Spirit and get a free expression. The event will be available from 9 May until 12 May, so players can give it a go throughout the weekend but will need to act fast.
In order to meet with the Season of Sanctuary Spirit, players will need to have finished up a few things first - so unfortunately, brand-new players won't be able to partake in the travelling spirit's event.
You'll need to have visited the Valley of Triumph and started the Hopeful Steward's fourth quest in Aviary Village. If you haven't finished the Steward's quest but have already started it, you can still meet with the Season of Sanctuary spirit available during this event.
If you meet all of the requirements, just head to the Sanctuary Islands at some point during the weekend and relive the Spirit's memories by interacting with them. Once you've done this, you'll get the Season of Sanctuary Spirit's free unique expression!
Remember that this event only lasts for a limited time, so if you want to meet with the traveling spirit, be sure to do it over the weekend.
