Alright r/VALORANT it's time for a conspiracy, so put on your tinfoil hats and let's dig in.

First, Icebox is a Kingdom research station. However, the question is what exactly is Kingdom researching there? Well, if we go by the context clues provided throughout the level, the first big thing you're likely to notice is an old ship stuck in the ice with cranes overhead.

What kind of ship is this? Well it appears to be Asian judging by the rooftops on the decks and a few other design features. Further, if you look around the map you'll notice something even more telling. There are suits of samurai armor in tanks and on laboratory tables.

As we all know samurai are Japanese warriors, and that settles part of the origin of the ship. So far all these clues are relatively obvious, but here's where it starts to get really interesting. If we take this information and then incorporate the battlepass there's more to be discerned.

As can be seen here, Kingdom is using the cranes to pull something out of the ship stuck in the ice. But what are they pulling out? Suits of armor? Radianite mined from long ago? Possibly bodies? The next clue comes further into the battlepass.

Now that we've seen the battlepass in addition to the map this card makes more sense. Besides looking very Gurren Lagann, this card is named 'secret lineage' and almost certainly represents the facemask portion of a samurai's armor. Whose lineage is it though? Kingdoms? The origin of radianites? A specific characters? Personally, I think it might be at least the last two. This leads us to the final card.

Now we all know this card at the end of each battlepass represents the next agent, but let's take everything we've learned so far and add it all together with the card. A memento mori is an object meant to serve as a remembrance of death. Samurai were famously ritualistically obsessed with death. The ship appears to be around Sengoku era in its design, which would be the height of samurai warfare. Do you know which Japanese clan was one of the greatest ship builders in the Sengoku era in real life? The Mōri clan.

Therefore, I propose that the agent after Skye will be an ancient radiant and possibly the first radiant. A samurai from the Sengoku period who was trapped in the ice and defied death due to his radiant powers until being discovered and studied by Kingdom at the Icebox station.

Lastly, keep in mind this map was originally meant to be released at the start of Episode 2 with said character, so it's highly likely that these map clues are related.
