Seaside Harbor Light

The Seaside Harbor Light is a location that appears in Sonic Boom: Rise of Lyric. It is a lighthouse-like tower found on Bygone Island which serves as a way to reach the Sky Citadel.

Description
The Seaside Harbor Light is located on a circular platform not far from the southern coast of Bygone Island. The entire structure resembles a lighthouse, with a circular entrance, a Crystal Lock in front and three rows of cyan orbs adorning the bottom and top. When activated, four small pillars extends from the top in midair and a column of light shoots into the sky. Due to being over a millennia old though, it has cracks in the surface and vines growing up along it.

Inside the Seaside Harbor Light is a teleporter that takes the users directly to the Sky Citadel. However, it is only designed to take two passengers, after which it become unusable.

History
The Seaside Harbor Light was seemingly created by the Ancients at least over a thousand years ago.

In the present day, Team Sonic came to the Seaside Harbor Light to find the final Chaos Crystal. Using the Twilight Crystal, the team unlocked and activated the Seaside Harbor Light, but when they attempted to use its teleporter to reach the Sky Citadel, only Knuckles and Amy got through it. As such, Sonic and Tails had to use the Tornado to reach their destination.
