It is Week 6 of Beyond Light, which means a new Penguin Souvenir is available in the game. You will need these for the Reuniting the Eventide Rookery Triumph if you want to go for the Splintered Title this season.
This guy can be found in the Riis Reborn area of the Eventide Ruins. Spawn in at Varik’s base, then head all the way north. When you arrive in Eventide Ruins make your way to the elevator that leads up to Riis Reborn. The exact location of the elevator is shown on the map below.
From there, make your way all the way through the Riis Reborn area until you come to the room with a raised door on the left, and another door in the back right. You should remember this area as the door in the back right was closed with a Stasis lock during the campaign.
In that right corner, you will find a yellow bar enemy called a Fallen Marauder. Kill him, and he will drop the Penguin. After that, take it back to the room beside Variks and put it in its place to complete this section of the Triumph.
If you forgot about some of the previous weeks, you can find all the locations you need here. There are only three more left to find, which will wrap up the Triumph. We are unsure at this time if there is any reward to be had from it, but a nice Penguin-themed Emblem would be good fun.
