The servers like Era and Zodiac are "free". You won´t have an Observer System there.

Q: What is an Observer System?
A: You will have 4 hours to play Graal on PC (except on Zodiac and Era cause like I said they removed it there). After the 4 hours are over, you can play like 7 minutes and you will have like 3 minutes break. Usually you don´t need to buy the gold subscription but that will remove that Observer System from your client for the time range you bought it.
With the gold subscription you can set more heads (with Observer System just Head0.png - Head15.png) and you can get fully hired on a server without any troubles.
