Since Foresee is a force power introduced in the Age of Rebellion Beta, I realize that this question might be better served in the AoR Beta boards, but I specifically want to task gamemaster's (Starmasters?) what they think.

Currently, one of my players is about to switch characters. He is retiring his Wookiee pilot for a Force Sensitive: Emergent . We already have a Force: Sensitive Exile in our party.

Since I know the switch will be coming up, I want to lead into it. My thought was to give the Exile a vision of the Emergent. The idea is the Emergent has been captured by the Hutt in which they are currently staying at and he is being used as entertainment in the fighting pits. My thought is during an evening of rest there, the Emergent would have a vision of the Exile. And at some point the next day, the Hutt would invite them to watch the fighting. (Yes I kind of stole a bit for Episode II of Dawn of Defiance).

But the problem is, the Exile doesn't have the Foresee force power. He does have the sense power, but I wanted it to come in the form of a vision. I want to make sure that I don't make foresee less enticing for future players in my game. For example, I don't want my players to ignore investing in foresee because I may have used force visions as a plot device in the past even when the player's character didn't have that ability.

What do you guys think?

I think its fine. I have done similar things with my Force sensitive exile. The important thing to remember is to not use it too often, and only as a plot/GM tool, i.e. the player cannot activate it at will, but you will either just give them a vision straight up no check, or ask them to roll the force die/dice (plus perhaps Discipline or straight Willpower depending), the result can then guide you as the GM to narrate the vision. I use it sparingly, and mostly in conjunction with the Sense power (in my head, not anything game mechanical about it really, just how I justify touching things and asking for checks )

[...] the player cannot activate it at will [...]

Everything you said makes good sense. I think this is probably the key right here. It might be the player will want to invest in Foresee later to show that he wants to hone his abilities to see visions, but for now they might come very sparingly.

Exactly, if one of them invests in (and somehow learns) Foresee, then it is different. Of course you can still use your own GM-activated visions, but the player now has the ability to attempt themselves, with the restrictions put in place by the Force power. I'm not aware of all those restrictions (as I'm still waiting for my AoR beta book), but from what I understand they do put restrictions on how far into the future, nothing in the past, and such stuff... The GM/plot visions that you as a GM initiate does not need to be bound by those restrictions, therefore being more powerful and informative.

Hm... What if they connected through the force? Basically, the Exile is in the palace, possibly meditating (if the Exile in question does in fact meditate), and then somehow connects to the Emergent. He cannot communicate with him, but through the force he can sense what is happening. Basically, he can see through the Emergents eyes and hear his thoughts, but he is unnoticed.

This could link the PCs, kind of like Revan and Bastilla from KotOR, and they could be obligated to help each other (wether or not this could become obligation is up to you). With this, you don't say that Forsee is useless as you might get it for free (which you might be able to, but only in dire situations), but you get the Exile to know about the Emergent. As the Exile knows the Emergent's thoughts, the Exile knows the Emergent is force sensative.

I'd prefer to make Forsee its own thing. It would take away the fun of getting the ability to see into the future if it can just happen anyways. Any Sensative can feel a disturbance or sense the force, but not all Sensatives can see the future. It adds a certain aspect to the game when getting an ability makes you special.

Still, this is just my thoughts on the matter.

I plan to do this soon but the visions will come through dreams so that is made clear the player has no conscious control over them.

I'd just do it narratively without worrying about whether that power is purchased until it is...and even then, upthread is a great suggestion: GM-driven visions for GM-pushed plot points compared to player-instigated visions triggered by rolling for the purchased Foresee power and the player trying to prophesize specific-ish info the character wants to find out.

Also, I wouldn't be surprised if the Emergent wants to take the Exile specialization eventually and vice versa, buying new Force talents and access to a possible total of Force Rating 3 is pretty tempting.
