Arcturus also Spica

Arcturus is special because it’s not moving with the general stream of stars in the flat disk of the Milky Way galaxy. Instead, Arcturus is cutting perpendicularly through the galaxy’s disk at a tremendous rate of speed . . . some 150 kilometers per second.

Arcturus has a high proper motion, two arc seconds a year, greater than any first magnitude star other than α Centauri. It is moving rapidly (122 km/s) relative to the Solar System, and is now almost at its closest point to the Sun. Closest approach will happen in about 4,000 years, when the star will be a few hundredths of a light year closer to Earth than it is today. Arcturus is thought to be an old disk star, and appears to be moving with a group of 52 other such stars, known as the Arcturus stream.[21]
In antiquity, Arcturus was closer to the centre of the constellation

Arcturus is mentioned both by Edgar Cayce and Arthur Ford. In one of Cayce's readings we see this:

Not that the Sun which is the center of the Solar System is all there is. For the entity has attained to even the realm of Arcturus... that center from which there may be an entrance into other realms of consciousness. And the entity has chosen in itself to return to earth for a definite mission.
