I will also mention the availability FFXIV Gold of a second profession here

I suggest specializing in the Fire Magic line at this point since it will allow you to gain the FFXIV Gold full potential of your newfound spells. You may also wish to simply rove around igniting any helpless foe that is unfortunate enough to cross your path. 

Roaming around and doing such is a great way to learn when to cast certain spells and just how little tanking you needed to be doing?

I will also mention the availability of a second profession here. Certain trainers are scattered throughout the areas that are willing to train you in a second class of your choice.

Armin Saberlin on the East side of town will give you a quest for a second profession and will point you in the direction of the trainer that teaches that profession. I suggest Monk as a secondary if you’re relatively new to the Guild Wars experience or simply caster classes in general. 

Once you’ve finished messing around here and gained a few levels (I suggest being level 5 or so), you can talk to Sir Tydus and enter into a storyline mission. This will take you to a PvP arena. 

After the NPCs finish talking you can start killing things. After finishing up this mission, you’ll get a cut-scene and then pop up in Post-Searing Ascalon.
