Hi - you could play again and choose another option and see for yourself
But nevertheless I will give you the answers that you seek
When you choose gold the watcher of souls says:
So you seek gold? Yet all you'll find is what the hunger for gold sows. Greed, envy, hatred and death!
And you will be attacked.
When you choose spica the watcher of souls says:
Your concern for the well-being of others does you great honour. Leave in peace. The dead will trouble you no more.
And there will be no more attacks from the undead in that part of the map.
