"terra" is the terracotta army that was buried at the tomb of Shihuangdi. It says it is located 30 miles or so east of Chang An (modern Xi'an) at Mount Li (Lishan).
"spires" is a bit tougher and I'm not sure what it is supposed to represent. It could be:
Yellow Crane Tower, but it wasn't built until 223 AD,
Bronze Pheasant Tower in Ye, but I think that tower is fictional or,
Yueyang Tower which was built by Lu Su some time after 194 AD (probably around 200 AD).
"sleeping" is a sleeping (or reclining) Buddha statue, but I can't find anything for a statue that existed during this time period. Most of what I have found weren't built until the Tang dynasty.
"havarak"... have no clue what that is supposed to be.
